Free Online XML XPath Evaluator & Tester
The XML XPath Evaluator & Tester is an interactive developer tool designed to test, validate, and execute XPath expressions against any XML document in real time. Whether scraping web feeds, configuring XSLT transformations, or writing automated tests for enterprise SOAP responses, it extracts matching XML nodes, attributes, and text nodes instantly directly in your browser.
1. How to Test XPath Expressions
Run XPath queries in three simple steps:
- Paste your XML document into the left editor or upload an .xml file.
- Enter your XPath expression into the query input (e.g. //book[price > 30]/title/text()).
- Click 'Evaluate XPath' to view matching elements, attribute strings, and node counts.
- Copy matching results or download as a text report.
2. Key Features
2.1 W3C XPath Compliance
Supports standard XPath axis queries, predicate filtering, wildcard selectors, attribute lookups, and scalar functions like count() and sum().
2.2 Match Count & Error Diagnostics
Displays instantaneous node match counts or detailed syntax error highlights if your XPath or XML contains malformed elements.
2.3 Serialized Node Output
Matching elements are rendered in full XML syntax with attributes and nested children preserved for direct copying.
2.4 Client-Side Processing
All expression parsing and XML evaluations are executed entirely in your browser without transmitting sensitive data over the network.
3. Common XPath Expressions & Syntax
3.1 Selecting Nodes by Tag Name
Use //tag to find all elements with that tag name anywhere in the document, or /root/tag for direct child selection.
3.2 Filtering by Attribute Values
Use predicates like //item[@id='101'] or //button[@type='submit'] to locate elements matching specific attribute criteria.
3.3 Positional Selection
Target specific array indexes using //record[1] for the first node, or //record[last()] for the final item in the collection.
3.4 Text and Substring Matching
Search within text nodes using functions like //title[contains(text(), 'Release')] or //category[text()='Technology'].
3.5 Numerical Comparisons & Aggregation
Filter numeric values with expressions such as //product[price > 50] or count(//product) to determine total occurrences.
4. Practical Use Cases
4.1 QA & Automated Test Verification
Test and refine XPath selectors for Selenium, Cypress, Playwright, and SOAP UI assertions before writing automated test scripts.
4.2 API Response Inspection
Inspect complex enterprise XML/SOAP responses to isolate nested transaction IDs, status codes, and error envelopes.
4.3 Feed & Sitemap Extraction
Verify queries for extracting URLs, lastmod timestamps, and priorities from XML sitemaps and RSS/Atom feeds.
4.4 XSLT Stylesheet Development
Quickly prototype and test XPath patterns used in template matches and value-of expressions before deploying XSLT stylesheets.
5. Frequently Asked Questions (FAQ)
5.1 What is XPath and how does it navigate XML?
XPath (XML Path Language) is a W3C standard query language designed to select nodes from an XML document. It uses path expressions resembling file system paths to traverse elements, attributes, and text nodes.
5.2 Why does my XPath return no results when namespaces are present?
If your XML uses default namespaces (e.g., xmlns='http://...'), bare element names in XPath 1.0 may not match. You can use local-name() queries such as //*[local-name()='tag'] to match elements irrespective of namespace prefixes.
5.3 Can I extract attribute values directly as plain text?
Yes. Append /@attributeName to your expression (for example, //user/@email). The evaluator outputs the extracted attribute values directly in the result pane.
5.4 Is my XML or XPath query sent to a server?
No. The XPath engine evaluates documents locally inside your browser's DOMParser and XPathEvaluator runtime. No XML data leaves your computer.
